Seiko continues its yearlong celebration of 145 years in business with a new quintet of limited-edition watches. This time, the connecting theme is color, with all five dials decorated in “Edo purple.”

The color has a rich cultural significance and deep ties to Seiko’s hometown of Tokyo, originally known as Edo, but it also just looks really good on a watch dial. The Prospex Speedtimer stands out for its stark departure from the muted black, white and steel or flashy warm colors typically found on racing chronographs.

The Prospex Speedtimer 145th Anniversary Limited Edition “Edo purple” follows the collection’s standard blueprint, featuring a 42mm stainless steel case topped with a fixed aluminum tachymeter bezel operated with dual button pushers flanking a fluted crown.

The eye-catching violet dial is enhanced with a sunburst finish and encircled by a metallic rehaut with a black rule-style seconds track. The beveled hour and minute hands and applied hour markers have gold-tone plating and white LumiBrite inserts.

A need for speed

This is a solar quartz version of the Prospex Speedtimer, powered by a Seiko Caliber V192 movement. It has a stated accuracy of ±15 seconds per month and will run for six months on a full charge.

The Panda-style black subdials consist of a synched 24-hour time at 3:00, a 60-minute totalizer at 6:00 and a small seconds at 9:00. A date window is tucked away at 4:30 with a white track on a black disc.

A particular plum

Edo purple is a traditional Japanese pigment, historically produced by layering red and blue vegetable dyes, and is associated with the Edo period’s merchant class. Seiko describes the hue as a deliberate callback to Japanese craft traditions rarely surfaced on sport watches.

It sits closer to a blue-leaning violet than the saturated purple Seiko used on its 2025 World Athletics Speedtimer SSC995, making the dial more restrained in person, according to the brand.

Availability and price

Personally, I would love to see the newest generation of automatic Speedtimer get the “Edo purple” treatment, especially because the color was recently applied to a solar Speedtimer. But this model is far more accessible at less than a third of the price, and we’ve already gotten a 145th Anniversary automatic Speedmaster.

Seiko’s “Edo purple” collection will be released in October 2026. The Prospex Speedtimer is priced at $750 and, in Seiko terms, is “limited” to 8,000 pieces.
